SPECIFIGATIQN forming part of Letters Patent No. 704,881, dated July 15, 1902. Application filedMay 12, 1902. Serial No. lO'LQlQL (No model.)

To all whmn it may concern: y

Be it known that I, ELEAZER KEMPSHALL, a citizenpf the United States, residing inBdston, in the county of Suffolk and State of Mas-j sachusetts, I have invented certain new. and useful Improvements in Playing Balls, of which the following is a specification.

This invention relates to playing-balls, and especially to those used in the game of golf. Its chief object is to increase the flying power of the ball, while reducing the liability of its becoming damaged in use.

In the drawings forming part of this speci-g fication, Figure 1 is a part-sectional View of a ball made in accordance with my present improvements. Fig. 2 illustrates a broad rub-' her band such as used in making a portion of the ball, and Fig. 3 illustrates a core partly" built up of bands such as shown in Fig. 2.

For a center piece 1 I prefer to employ firm but compressible rubber. It is preferably inthe form of a solid sphere, although, if desired, it may be otherwise constructed. To this center piece I a'pplya succession of broad thin rubber bands 2, forming a complete core,

- as shown at 2*, Fig. 3, and upon this core I applya shell 3, of plastic material,preferab1y gutta-percha, and preferably holding. the core under high compression. Thematerial of the bands 2 is preferably much softer than that of the center piece 1 and all'i of said bands are highly tensioned upon the core,

thereby actively resisting distortion of the ball, so that when it is struck the reaction from the blow is hastened and it receives a powerful impetus and iiies a great distance.

By means of my present improvements I' overcome the liability present in the usual continuous-rubber-thread cores of bursting when a fewof the threads are cutthrough by a blow from a club or otherwise. It will be I seenthat owing to the breadth of the bands none of them is likely to be severed or to reiceive such an extensive out as would cause itto break, and also that even if one should break 'sioned thereon and forming a larger sphere,

and a shell of plastic material upon said sphere.

2. A playing -ball comprising a yielding center piece, a series of independent, endless,

"broad, thin rubber bands independently ten sioned thereon and forming a larger sphere,

and'a shell of plastic material holding said sphere under compression.

, 35A playing ball comprising a sphere of solidrubber; a succession of independent, endless, broad rubber bands independently tensioned thereon and forming a larger sphere; and a shell of plastic material upon said sphere.

.4; A playing-ball comprising a sphere of solid rubber, a succession of independent,

endless, broad bands of softer rubber independently tensioned thereon and forming a larger sphere, and a shell of plastic material upon said sphere.
